What kind of quote is that? Markets are clearly many-to-many by definition. Money doesn't even have a meaning or value without markets. It's just paper without markets.
I think the idea is that "more capable" participants tend to make money off of "less capable" participants. And there are a lot more of the "less capable" ones.
Markets are like ecosystems, they are an emergent property of the aggregated activity of many participants. Yes, some of those participants will end up at the top of the food chain. But that's going to happen regardless of what you do.
